US 'Crowdsourcing' Border Security

I'm not going to get involved in the politics of this, but its crowdsourcing at work: Web users to 'patrol' US border

"A stronger border is what Americans want and it's what our security demands and that is what Texas is going to deliver," Mr Perry said. The cameras will cost $5m (£2.7m) to install and will be trained on sections of the 1,000-mile (1,600km) border known to be favoured by illegal immigrants. Web users who spot an apparently illegal crossing will be able to alert the authorities by telephoning a number free of charge.
